Carbon-14 is an element that loses about 10% of its mass every millennium (i. e., 1000 years). a sample of carbon-14 has 600 grams. write a function that gives the sample’s mass in grams, s(t), t millennia from today.

The function that gives the sample's mass after t millennia can be derived

from the equation for decreasing rate formula.

Reasons:

The rate at which carbon-14 loses its mass = 10% per millennium

The initial mass of the sample of carbon-14 = 600 grams

Required:

A function that gives the mass of the sample in grams S(t), in t millennia

from today.

Solution:

The formula for decreasing rate is; y = a·(1 - r)ˣ

Where:

y = S(t) = The mass of the sample after t millennia

x = t = The number of millennia

a = Initial mass = 600 grams

r = The decay rate = 10% = 0.1

By plugging in the above values, we get;

a

step-by-step explanation:

jjddbdhid r

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
